There are some beautiful and useful mechanical keyboards on the market but only a few of them are made for Mac. Matias Keyboards have a Mac layout and they also sell mechanical keyboards. But their keyboards are not illuminated. Das Keyboard has some Mac models but they also do not come illuminated. I could not find a Mac layout mechanical keyboard that has not just illuminated keys, but keys for which their colour could be adjusted. Most modern gaming keyboards offer this function.
Tutorial on how to install and setup JInput on Mac OS X using Eclipse. This will enable you to use different input devices in your Java programs.
Using mouse, keyboard, joysticks and other input devices in your Java software is much easier using JInput. Unfortunately, the documentation on how to install and setup the software is short and difficult to follow. I was struggling for days getting it to work with Eclipse on Mac OS X 10.12.6. My first approach was to use Maven to install JInput. The excellent M2Eclipse plugin provides good support for Maven. Unfortunately, the pre-configured Maven Repository does not include JInput. I was unable to configure Maven/Eclipse to connect to The Central Repository to download JInput from there. Okay, I am not a fulltime Jave programmer and maybe it would become clear to me eventually. In the meantime I got it to work manually. I hope that this tutorial will help you in your project. I used Mac OS X and I cannot guarantee it will work on any other platform.
